I wonder if anyone could help me, I have recently installed a complete loft access kit to get into the loft to board it out for storage. After doing a diy survey I have realised that my ceiling joists are 50mm wide by 90mm high and 4000mm long, each joist is 300mm apart. Each joist sits on top of an external wall and the other end on an enternal wall that is in the middle of the house I would only be boarding 1750mm from the central wall to the front wall and 1750mm from central wall to the back wall by 4500mm which is the width of house. The joists are not bowing, bouncy or bent the property is end of terrace 1900 built. So to my question could I put loft insultation between the joists and screw down loft Panel boards on top safely?
or any other ideas, comments and suggestions would be greatly appreciated
